Definitions of sodium

  1. a silvery soft waxy metallic element of the alkali metal group; occurs abundantly in natural compounds ( especially in salt water); burns with a yellow flame and reacts violently in water; occurs in sea water and in the mineral halite ( rock salt)
  2. A common metallic element of the alkali group, in nature always occuring combined, as in common salt, in albite, etc. It is isolated as a soft, waxy, white, unstable metal, so readily oxidized that it combines violently with water, and to be preserved must be kept under petroleum or some similar liquid. Sodium is used combined in many salts, in the free state as a reducer, and as a means of obtaining other metals ( as magnesium and aluminium) is an important commercial product. Symbol Na ( Natrium). Atomic weight 23. Specific gravity 0. 97.
  3. An element that is a member of the alkali group of metals. It has the atomic symbol Na, atomic number 11, and atomic weight 23. With a valence of 1, it has a strong affinity for oxygen and other nonmetallic elements. Sodium provides the chief cation of the extracellular body fluids. Its salts are the most widely used in medicine. ( From Dorland, 27th ed) Physiologically the sodium ion plays a major role in blood pressure regulation, maintenance of fluid volume, and electrolyte balance.
  4. A waxy, white, alkaline metallic element, in nature always occurring in combination, as in common salt, alum, borax, etc.
  5. Metallic base of salt.
  6. A yellowish- white metal, the base of soda.
  7. A light whitish metal.
  8. A silver- white alkaline element; the base of soda.
  9. The metallic base of soda.
  10. The metallic base of soda, soft, of a silvery lustre, and lighter than water.
